Attributes

JET Custom Elements

JET components are implemented as custom HTML elements. In addition to the component attributes documented in this page, JET components also support standard HTML global attributes like id and aria-label.

The JET data binding syntax can be used to define both component and global attributes through the use of dynamically evaluated expressions. All attributes (component and global) support attribute-level binding by prefixing the attribute name with ":" (e.g. :id="[...]"). When using attribute-level binding, all expression values are treated as strings. Additionally, component attributes support property-level binding by using the attribute name directly with no ":" prefix. When using property-level binding, the expressions should evaluate to the types documented by the corresponding attributes. Property-level binding is strongly recommended over attribute-level binding for component attributes.

A detailed description of working with custom HTML elements can be found in: JET Custom Element Usage.

JET SwipeActions Component

Description: SwipeActions can be added to an item in ListView to add swipe-to-reveal functionality when user swipes an item. The SwipeActions contains a start and/or an end slot, each represent the action bar to display when user swipes in a particular direction. The oj-option element is used to represent each item in the action bar.


<oj-list-view>
  <template slot='itemTemplate'>
    <li class='oj-swipeactions-container'>
      <oj-swipe-actions on-oj-action='[[listener]]'>
        <-- Content of item goes to the default slot -->
        <span>Item content</span>
        <-- Display when user swipes from end to start of the item -->
        <template slot='end'>
          <oj-option>Action 1</oj-option>
          <oj-option class='oj-swipeactions-default'>Action 2</oj-option>
        </template>
      </oj-swipe-actions>
    </li>
  </template>
</oj-list-view>

Icon

SwipeActions currently supports the rendering of icon for each options. To render the icon, the startIcon slot of the oj-option should be specified. See the oj-option doc for details about accepted children and slots.

Styling

The following CSS classes can be applied by the page author as needed.

Class Description
oj-swipeactions-container Designed for use with item in oj-list-view that contains the oj-swipe-actions element, specifically this will remove the padding around the content of the item so that the swipe actions can take the full height.

Is applied to the root of each item in oj-list-view containing the oj-swipe-actions element.

oj-swipeactions-neutral Designed for use with an action item that shows more available actions that users can perform.

Is applied to the oj-option element that represents the action item.

oj-swipeactions-attention Designed for use with an action item that tags the associated item in oj-list-view.

Is applied to the oj-option element that represents the action item.

oj-swipeactions-danger Designed for use with an action item that performs an explicit action like deleting the associated item in oj-list-view.

Is applied to the oj-option element that represents the action item.

oj-swipeactions-default Designed for use with an action item that should get all the space when user swipes pass the threshold distance. This is usually the last item within the template.

Is applied to the oj-option element that represents the default action item.

Accessibility

SwipeActions will display skip links that allow users to access swipe actions when the element has focus. This implies that when SwipeActions is a child of ListView, the skip links will become accessible when user hits the F2 key.

Although the swipe actions are accessible with the keyboard using skip links, it is recommended that applications provide an alternative way for the users to perform all the swipe actions.

Touch End User Information

Target Gesture Action
oj-swipeactions-container element Swipe Reveals the swipe actions. Depending on the distance relative to the target is swiped, the oj-swipe-actions will either be closed (swipe distance too short), opened, or the default action is performed (swipe distance passed a certain threshold).
oj-swipeactions-container element Pan Reveals the swipe actions. If a default action is specified, the default action will take over all the space of other action items after the user panned past a certain distance.
oj-swipe-action element Tap Triggers the action associated with the swipe action.

Keyboard End User Information

Target Key Action
ListView Item F2 If SwipeActions is a child of ListView, then pressing F2 key on the ListView item will focus on the SwipeActions, which cause it to display the show actions links for the start and end swipe actions.
Show actions link Enter Reveals the start/end swipe actions.
Hide actions link Enter Hides the start/end swipe actions.
Swipe action Enter Trigger the action associated with the swipe action.
Esc Hide the swipe actions.
Tab Navigate to the next swipe action. If it is the last swipe action, navigate to the hide actions link.

Note: Application logic should not interact with the component's properties or invoke its methods until the BusyContext indicates that the component is ready for interaction.

Slots

JET components that allow child content support slots. Please see the slots section of the JET component overview doc for more information on allowed slot content and slot types.

Default

When using SwipeActions within ListView, any content for the item in ListView should be added as child element in SwipeActions.

contextMenu

The contextMenu slot is set on the oj-menu within this element. This is used to designate the JET Menu that this component should launch as a context menu on right-click, Shift-F10, Press & Hold, or component-specific gesture. If specified, the browser's native context menu will be replaced by the JET Menu specified in this slot.

The application can register a listener for the Menu's ojBeforeOpen event. The listener can cancel the launch via event.preventDefault(), or it can customize the menu contents by editing the menu DOM directly, and then calling refresh() on the Menu.

To help determine whether it's appropriate to cancel the launch or customize the menu, the ojBeforeOpen listener can use component API's to determine which table cell, chart item, etc., is the target of the context menu. See the JSDoc of the individual components for details.

Keep in mind that any such logic must work whether the context menu was launched via right-click, Shift-F10, Press & Hold, or component-specific touch gesture.

PREVIEW: This is a preview API. Preview APIs are production quality, but can be changed on a major version without a deprecation path.

The end slot is used to specify the action bar options that appear when user swipes from end to start on its container. The slot must be a <template> element.

When the template is executed, it will have access to the parent binding context. For example, in the case of ListView, $current should return the data of the row containing the swipe actions.

Attributes

translations :object|null

A collection of translated resources from the translation bundle, or null if this component has no resources. Resources may be accessed and overridden individually or collectively, as seen in the examples.

If the component does not contain any translatable resource, the default value of this attribute will be null. If not, an object containing all resources relevant to the component.

If this component has translations, their documentation immediately follows this doc entry.
